We had similar problem few month ago when migrating from hammer to jewel. We encountered some old bugs (which were declared closed on Hammer !!!l). We had some OSDs refusing to start because of lack of pg map like yours, some others which were completly busy and start declaring valid OSDs losts => the cluster was flapping. These OSDs were localized on some hosts only, and these hosts were first in giant then in hammer version before jewel.Hosts which never knew giant were OK. So in fact, we ported some old bugs from giant to jewel !!! The solution was to isolate one by one the hosts which were one day in Giant and to recreate them with a fresh jewel version. That solved the problem (but it took a lot of time). I hope this will help you ... _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
